Abstract

Experimental output characteristics of 1.2 kW cw CO₂ laser are analyzed in order to estimate the small signal gain and saturation intensity parameter. Results obtained from approximate expressions for output power under homogeneous broadening conditions of a non-flow laser are compared with measured ones. Satisfactory agreement is obtained for gain coefficient in the linear range of the laser output characteristics. The results concerning saturation intensity seem to be overestimated due to the flow effect.
